The initial public reception to Prince Harry's relationship with American actress Meghan Markle was largely positive, with the late Queen Elizabeth II reportedly viewing her as a "breath of fresh air." Their 2018 wedding was met with widespread celebration.

However, a detailed timeline suggests a subsequent decline in the couple's popularity following their decision to step back from senior royal duties and relocate to California. The narrative of their journey from "royal sweethearts" to their current status is marked by a series of events that have contributed to this perceived shift.

Since leaving their royal roles, the Duke and Duchess of Sussex have pursued various media ventures and public engagements. While these endeavors have aimed to establish their independent brand, they have also been met with mixed reactions and scrutiny, contributing to the ongoing public discourse surrounding their popularity.
